Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, specific embodiments of the invention are elaborated below in conjunction with accompanying drawing.At this, illustrative examples of the present invention and explanation thereof are used to explain the present invention, but not as a limitation of the invention.
Embodiment one
In the embodiment of the invention, as shown in Figure 1, the method for obtaining neighbor information of base station comprises:
Wherein, the described neighboring BS information that has disposed can be the Neighboring Relation Table of above-mentioned base station maintenance, also can be the PHY_ID etc. of the adjacent area of base station maintenance.
The base station is by sending to UE to the neighboring BS information that has disposed, make UE can discern the character of adjacent area, promptly, if the relevant information of the adjacent area of not reading in the neighboring BS information that has disposed (for example, PHY_ID or the GCI information corresponding with PHY_ID), represent that then this adjacent area is to find the adjacent area certainly, at this moment, UE obtains the PHY_ID of this adjacent area and corresponding GCI information, and PHY_ID and the corresponding GCI information with the adjacent area that obtains sends to the base station then.
By as above step, control request is measured by sending in the base station, just can obtain the GCI information that oneself finds the adjacent area, thereby need not to issue once more ANR periodic measurement control request, reduce the number of times of sending measuring control request, saved the step of switching, reduced handoff delay.
Optionally, in step 101, can also comprise in the measurement control request that the base station issues that the neighboring BS information and the GCI that have disposed report indication, this GCI reports indication to be used for indicating terminal and reads corresponding GCI information.Correspondingly, in step 102, just carry the GCI information that GCI reports the adjacent area that indication will report in the indication in the measurement report that the base station receives.Like this, the base station just can obtain to indicate the GCI information of the adjacent area that will report, thereby need not to issue once more ANR periodic measurement control request, has reduced and has measured the number of times that control request issues, and has reduced handoff delay.
GCI reports indication to comprise following 3 types:
(1) GCI reports and is designated as all (all), represents that then the GCI information of each measurement adjacent area that UE will read all reports, and the GCI of the type reports indication to use at the networking initial stage;
(2) GCI reports and is designated as from finding adjacent area (onlyanr), represents that then the GCI information of finding the adjacent area certainly that UE will read reports;
(3) GCI reports and is designated as best adjacent area (strongest), represents that then the GCI information of the top-quality adjacent area that UE will read reports.
Like this, terminal just can report GCI to report the indicated GCI information of indication to the base station, issues ANR periodic measurement control request once more thereby need not the base station, has reduced and has measured the number of times that control request issues, and has reduced handoff delay.
Embodiment two
Correspondingly, as shown in Figure 2, the adjacent zone information reporting method of terminal comprises:
Step 201 receives the measurement control request that the base station issues, and comprises configured neighborhood information in this measurement control request.
Step 202, according to configured neighborhood information, the adjacent area that identification is found obtains from the GCI information of finding the adjacent area for when finding the adjacent area.
Particularly, UE is according to configured neighborhood information, and at first whether the adjacent area of identification discovery is to find the adjacent area certainly, if, then read this from the broadcast channel (BCH) of finding the adjacent area, obtain this from the GCI information of finding the adjacent area.
Step 203 reports the GCI information of the adjacent area of acquisition to described base station.
For example, UE will contain from finding that the GCI information of adjacent area and physical I D information report the base station by measurement report.
The base station is after receiving measurement report, the neighboring BS information that reports at UE, recognizing after finding the adjacent area and can initiate the adjacent area switching flow according to the GCI information of this adjacent area that receives, need not to issue once more ANR periodic measurement control request, than prior art, the embodiment of the invention has reduced measures the number of times that control request issues, and has reduced handoff delay.
Optionally, in step 201, can also comprise in the measurement control request of reception that the neighboring BS information and the GCI that have disposed report indication, this GCI reports indication to be used for indicating terminal and reads corresponding GCI information.Correspondingly, in step 202, terminal reports indication to read the broadcast channel (BCH) of adjacent area according to GCI, obtains the GCI information of corresponding adjacent area.It can be that GCI in the foregoing description one reports indication that this GCI reports indication.
Particularly, if reporting, GCI is designated as from finding that the GCI of adjacent area reports indication, i.e. indication reports from the GCI information of finding the adjacent area, then UE just can discern the character (as whether being from finding the adjacent area) of the adjacent area of discovery according to configured neighborhood information, if be identified as when finding the adjacent area, then read this from the broadcast channel of finding the adjacent area, obtain described from the GCI information of finding the adjacent area; Report the GCI that is designated as whole adjacent areas to report indication as if GCI, then the GCI information of all adjacent areas of UE reporting measurement; If GCI reports the GCI that is designated as adjacent area best in quality to report indication, the GCI information of the adjacent area best in quality arrived of UE reporting measurement then.
Like this, terminal just can report GCI to report the indicated GCI information of indication to the base station, issues ANR periodic measurement control request once more thereby need not the base station, has reduced and has measured the number of times that control request issues, and has reduced handoff delay.
Embodiment three
Fig. 3 in the present embodiment at the interaction diagrams that carry out adjacent area base station and terminal when switching, Fig. 3 be the base station of correspondence and the mutual schematic diagram of terminal.Base station and terminal interaction flow process comprise:
Step 301, base station under the current area A issues event type and measures control request (Mc, Measurement configuration), carries GCI in this measurement control request and report indication and configured neighborhood information (as the Neighboring Relation Table that has disposed) to UE.
Described GCI reports indication to be used to indicate UE to report the GCI information of specifying the adjacent area, and the adjacent area of described appointment can be spontaneous existing adjacent area, all adjacent areas or the top-quality adjacent area that UE measures.Here, the adjacent area of appointment is for when finding the adjacent area, and this GCI reports indication to be called from finding that the GCI of adjacent area reports indication; When the adjacent area of appointment was all adjacent areas, the GCI that this GCI reports indication to be called all adjacent areas reported indication; When the adjacent area of appointment was top-quality adjacent area, the GCI that this GCI reports indication to be called optimum adjacent area reported indication.
Above-mentioned GCI reports indication can be arranged in the indication information element (as the reportInd cell), and this indication information element can be carried in the measurement control request that the base station issues.
Step 302, UE receives the measurement control request that the base station issues, and reports indication to read the GCI information of corresponding adjacent area according to the GCI in the request.
Particularly, if reporting, the GCI in the measurement control request is designated as from finding that the GCI of adjacent area reports indication, i.e. indication reports from the GCI information of finding the adjacent area, then UE just can discern the character (as whether being from finding the adjacent area) of the adjacent area of discovery according to configured neighborhood information, if be identified as when finding the adjacent area, then read this from the broadcast channel of finding the adjacent area, obtain described from the GCI information of finding the adjacent area; Report the GCI that is designated as whole adjacent areas to report indication as if GCI, then the GCI information of all adjacent areas of UE reporting measurement; If GCI reports the GCI that is designated as adjacent area best in quality to report indication, the GCI information of the adjacent area best in quality arrived of UE reporting measurement then.
For example, the adjacent area of finding as UE is PHY_ID 5, and after receiving the measurement control request that eNB issues, configured neighborhood information identification PHY_ID 5 adjacent areas of measuring in the control request by traversal are for finding the adjacent area certainly.And UE reports the indication decision whether to obtain the GCI information of PHY_ID 5 adjacent areas by the BCH channel of this adjacent area according to the GCI that measures in the control request.
Report indication when GCI reports the GCI that is designated as whole adjacent areas, promptly GCI reports indication to be set to all, and then UE reads the GCI information of the adjacent area of each measurement; Be designated as from finding that the GCI of adjacent area reports indication when GCI reports, promptly GCI reports indication to be set to reportGCI, and then UE reads from the GCI information of finding the adjacent area; Report indication when GCI reports the GCI that is designated as adjacent area best in quality, promptly GCI reports indication to be set to reportStrongestCells, and then UE reads the GCI information of the adjacent area best in quality that measures.
Alternatively, in concrete implementation process, the base station also can issue the measurement control request of only carrying configured neighborhood information in the step 301, like this, UE still can be according to the configured neighborhood information that receives, the character of identification adjacent area, that is, whether the identification adjacent area is from finding the adjacent area., read this from the broadcast channel of finding the adjacent area, and obtain for when finding the adjacent area in UE identification adjacent area from the GCI information of finding the adjacent area, and execution in step 303.
Step 303, UE sends measurement report to eNB, reports corresponding adjacent area PHY_ID and GCI information.
For example, be designated as all if GCI reports, then UE is to the GCI of all adjacent areas of eNB reporting measurement information; Be designated as reportGCI if GCI reports, then UE reports from the GCI information of finding the adjacent area to eNB, promptly comprises the GCI information of PHY_ID 5 adjacent areas.Be designated as reportStrongestCells if GCI reports, then UE is to the GCI information of the adjacent area best in quality that the eNB reporting measurement arrives.
Step 304, eNB receives the measurement report of UE.
If comprise in the measurement report of UE from finding adjacent area PHY_ID 5 and GCI information, then the base station can be according to the neighboring BS information identification adjacent area PHY_ID 5 that has disposed for finding the sub-district certainly, so the GCI information according to adjacent area PHY_ID 5 is initiated switching flow, and need not to issue once more ANR periodic measurement control request.
If comprise the GCI information of the adjacent area best in quality that measures in the measurement report of UE, switching flow can be initiated with this adjacent area as the target adjacent area in the base station.
Even carry the GCI information of all adjacent areas in the measurement report, because during the UE reporting subdistrict, RSRP (Reference Signal Received Power), the RSRQ (Reference Signal Received Quality) of current area can be reported the base station in the lump, therefore the base station is by these two kinds of indications, quality that can a sub-district of Comprehensive Assessment, before switching, sort by service quality, and the Target cell that decision is switched according to this communication quality.
In order to realize above-mentioned steps, in the embodiment of the invention existing measurement control request is issued corresponding protocols and make amendment.
It is as follows that existing measurement control request issues protocol contents:

Shown in above-mentioned agreement, when measurement control triggering type (triggerType) was incident (event), existing protocol can't report GCI information in measurement report.Only when periodically (periodical) measurement control request issues, just have the option that GCI reports.Therefore the way of prior art is: if UE has reported one from finding the adjacent area, the base station need obtain this from the GCI information of finding the adjacent area, the ANR that just need issue one-period measures control request, could trigger UE like this and report corresponding to the GCI information of finding the adjacent area.
The embodiment of the invention issues protocol contents to existing measurement control request and makes an amendment slightly, amended theing contents are as follows:

As implied above, the reportGCI and the reportStrongestCells that in the present embodiment periodicity (periodical) are measured in the control cell extract outside the triggering type (triggerType), and are arranged in the reportInd cell that increases newly.Like this, UE reports the ability of GCI will no longer be subjected to measuring the restriction that control triggers type.For example, when the sending measuring control request, UE is from finding that the communication quality of adjacent area PHY_ID 5 is best, and reportInd cell attribute is set to reportStrongestCells, UE will obtain the GCI of PHY_ID 5 adjacent areas and fill measurement report and report to eNB by BCH, thereby removed the process that eNB issues ANR periodic measurement control request once more from, for the flow process of follow-up switching has been saved the stand-by period.
The measurement control of revising in the embodiment of the invention issues in the agreement, and it is optional cell that the reportInd cell is measured in the control at event type, rather than essential cell.Do not comprise the reportInd cell if event type is measured in the control, and UE reported and find the adjacent area certainly, then the base station also needs to issue periodic measurement control.In order in carrying out the periodic measurement process, to use the reportGCI cell, and do not influence the regulation of former agreement, stipulate in the present embodiment, when carrying out periodic measurement, must carry the reportInd cell.
For UE, report the related protocol of GCI correspondence to be described as follows by measurement report:

In this agreement, cell globalCellIdentity belongs to Optional Field.Be UE only when receiving that periodically (periodical) measures control request, according to the attribute in this periodic measurement control cell: reportStrongestCells or reportGCI, select corresponding GCI information to report.When carrying out event mode measurement control,, then can't report corresponding GCI information by regulation UE owing to can't select these attributes.If the base station adopts the measurement control of the invention described above embodiment to issue agreement, then UE can be according to the reportInd cell indication of measuring control, the dynamic action of selecting its measured adjacent area GCI information that reports, promptly, indication according to the reportInd cell reports GCI information, thereby has strengthened the control ability of eNB to the UE action.
If UE does not support the reportInd cell, the base station can be discerned by the measurement result that UE reports, and is recognizing UE when not reporting corresponding GCI information, and GCI information can be realized obtaining by issuing ANR periodic measurement control request in the base station.
In the present embodiment, report indication by in measuring control request, adding sub-district GCI, indication UE requires to report the GCI information of respective cell according to the base station, make the base station after receiving measurement report, need not to issue once more ANR periodic measurement control request, reduced and measured the number of times that control request issues, reduced handoff delay.
